Solution

An email address consists of two parts, the username (or name) and the domain name, separated by the "@" symbol. The domain name typically includes a top-level domain (TLD) such as .com, .org, .net, .edu, .gov, or others.

Option (a) is incorrect because it contains two "@" symbols, which is not a valid format for an email address.

Option (c) is incorrect because it is a website URL, not an email address.

Option (d) is also incorrect because it is not a valid format for an email address. A valid domain name should follow certain rules, such as not containing spaces and having a TLD.

Therefore, the correct answer is (b) name@website.info.
